' MOLD FOR FORMINGPOUBED BRICKS 0R BLOCKS.

To all whom it may concern i Be it known that I, Cnoir. L. VVATERMAN, a citizen of the United States, residing at Milford, in the county of Dickinson and State of Iowa, have invented certain new and useful Improvements in Molds for Forming Poured Bricks or Blocks, of which the following is a specification, reference being had to theaccompanying drawings.

My invention relates to devices for molding plastic materials, and particularly to devices for molding bricks or blocks to be used in building construction.

One object of my invention is the provision of a very. simple, easily handled, easily set up mold wherebybricks or blocks of concrete or other plasticmaterial may be readily molded, the mold being so constructed that it may be readily taken apart when necessary and so formed that bricks or blocks of different sizes may be molded by the same apparatus. l

A further object of theinvention is the provision of a mold so constructed that either an ornamental or a plain face may be given to the brick or block.

Still another object of the invention is to so construct the mold that, if desired, binding bricks or blocks may be molded therein.

Other objects willappearin the course of the following description. V

My invention is illustrated in the accompanying drawings, wherein:

Figure 1 is a plan view of my improved mold; Fig. 2 is an end elevation partly broken away; Fig. Sis a fragmentary top plan view of another arrangement of. the mold partitions; Fig. t is a like view to Fig. 3, but showing still another arrangement of the mold partitions; Fig. 5 is a fragmentary longitudinal section of the mold; "Fig. 6 is a perspective detailed view of the binding brick formed upon the pallet 18; Fig.7 is a perspective detailed view of the pallets 16; Fig. 8 is a perspective detailedview of one of the side walls 14:;Figr9 is aperspective detailedviewshowing the manner in which thepartition plates engagelwith the middlewall. I

Referring to the drawings, 2 designates the base of. the mold which may be made of any suitable material and has a fiat upper face and is supported by the longitudinally extending beams 3. Extending longitudi- Patented May 9, 1916.

nally with the member 3 is the wall l which is fixedly mounted upon the base 2 in any suitable manner, as by the U-shaped strip 5 which extends over one end of the partition Wall and is held to the base 2 by means of screws. At its opposite end the partition wall 4 is supported by means of a bracket 6 U-shaped in plan and having ears 7 whereby it is attached to the base 2. As before remarked, this partition wall 4 is held rigidly to the base but may be removed by lifting up that end of the partition wall 4 engaged with the bracket 6 and then slipping the parti tion wall out from under the strip 5. Thus while the partition wall 4 is easily support-- ed upon the base in relation tothe sidewalls 8 andt), it may, however, be removed from the base entlrelyo Coacting with the partition wall 4: are a pair of movable side walls 8 and 9. These walls of course extend parallel to the walla, and the walls are held in this parallel relation and firmly connected to the base 2 by means of the angular brackets 10. These brackets simply bear against thewalls and have outwardly extending baseswhich are slotted as at 11 for the passage of bolts or screws so that they maybe rigidly clamped in place.

- The inner face of the wall 8 is formed with notches 11 spaced a predetermined distance apart, and theconfronting face of the wall tis also formed with notches 12 spaced the samedistance apart as arethe notches 11 Theinner face of the wall 9 isalso formed withnotches 11 and like the wall 8 these notches are formed upon the confronting face-of the wall 4. These notches are adapted to receive the transversely extending partition plates 13 or 14, these partition platesholding the wallsS andQ spaced from the wall 4:. Preferably, both faces of the wall 4 between the notches are lined with re-' and other side walls used having notches 11 nearer together or farther apart.

For the purpose of supporting the molded mass of semi-plastic material within the mold spaces defined by the vertical walls, I provide the pallets 1.6, 17 and 18. These pallets are all the same except that they are of different size, and each pallet has preferably a smooth upper face and has depending feet or lugs 19 formed upon its under face supporting. the under face of the pallet about three quarters of an inch above the hold the lining plates in place by hearing against the lining plates above their lower edges.

Attached to one end of the base 2 i a rail 20 extending exactly at right angles to the partition wall 4 and against which the walls 8 and 9 may be abutted so as to bring these walls into such a position that the notches 11 in these walls will be exactly opposite the notches 12 in the wall 4.

The wall 8 and the wall 4 in addition to the notches 11 and 12 are likewise provided adjacent one end with the notches 21 for the purpose which will now be described.

It is often desirable to mold a binding brick of the form shown in Fig. 6. This brick, as will be seen from Fig. 6, is angular in form. The brick is ten inches long and the bottom of the main portion of the brick is ten inches wide. At one end the brick 22 is recessed, as at 23, and is laterally extended as at 24.' The distance between the 7 wall of the recess 23 and the end wall of the portion 24 i eight inches. Thus this binding or tie brick is in plan view as if two bricks had been laid together with the side edge of one brick abutting against the end edge of another brick and the first-named brick offset with relation to the secondnamed brick. By this construction the tie brick when laid up in the wall, looks exactly the same in effect as the other brick but extends; inward across the space between the inner and outer walls and the portion in the inner end'takes its place in the bricks of the inner wall and has exactly the same form as these bricks. For the purpose of molding these tiebri'cks, I provide the pallet 18', previously referred to, which is twelve inches in length and eight inches wide. One of the partitions 13 is moved down to the end notch 21 in order to accommodate this pallet and the oppositely disposed plates 25. These plates are twelve inches long by two and one-half inches high. They are made of sheet brass or sheet iron, or preferably of iron, and they may either be fastened rigidly to the form rails or walls 9 and4 or left loose, as circumstances may direct.

Cores 26 may be disposed upon the pallet to provide for the angular formation of the tie brick.

It will be seen that with the construction illustrated full sized bricks may be formed between the walls 4 and 9, these bricks being four inches wide, two inches thick, and eight inches long, that is, of standard size, and, asiillustrated in Fig. 2, between the wall 4 and the wall 9, bricks half this size may be made. If, however, it is desired to form full sized bricks on both sides of the wall 4, the wall 9' may be shifted outward and engaged with screws or bolts 27, and in that case the partition walls 14 may be used between the walls 4 and 8 in the same manner that the partition walls 13 are shown as being used (see Fig. 3). There is no dif ference between the walls 13 and 14, except in size. The wall 8 is likewise adjustable with relation to the wall 4 so that only half sized bricks or blocks may be made, as in Fig. 4, if desired. It will thus be seen that my mold is adapted to form either full sized bricks, half sized bricks, or tie bricks. v

he partition plates 14 and the partition plates 13 may be either plain or so formed as to give an ornamental contour to the br1ck. Thus, as illustrated in Fig. 8, the partition plate 14 (and the same applies to the partition plate 13) is shown as being figuration so as to simulate ashler or cut I have not illustrated the many stone. 7 ways in which these plates 15, 13 and 14 may be formed to give an ornamental contour to the face of' the black and an ornamental finish thereto, as this will be obvious to any one skilled in the art.

In the use of'my invention the mold is set up to form bricksof the desired size, and

then ,the plastic material is poured into By the the molds and allowed to set until it is i hard when the partitions between the bricks may be removed and the blocks removed from themold. It is of course to be understood that the inner faces of the mold walls and of the pallets are to be coated with paraflin' or oil in order to prevent the plastic material sticking to the walls.

It will be seenthat I have provided a mold in which bricks or blocks may be made without tamping or pressing. ther provide a mold which may be used either for forming ordinary bricks, half bricks, ortie bricks, these tie bricks going through both walls and holding the walls I furabutting against said rail, the confrontingtogether, thus doing away With the use of ordinary steel ties. The half bricks are capable of use on either side of doors and windows, thus avoiding the breaking of bricks and at the same time providing for a face which is uniform without full sized bricks. I further provide a mold which may be used for forming an ornamental contour upon the face of the brick and in which the partition plates having the ornamental configuration thereon may be readily changed as it maybe desired.

Having described my invention, what I claim is: I

1. A mold for building blocks comprising a base, a fixed longitudinally extending partition wall, a rail mounted upon the base and extending at right angles to the partition wall, removable side walls mounted on each side of the fixed partition wall and faces of the fixed and movable side Walls being formed with vertical grooves, removable partition plates disposable in said grooves, and means for holding the outer side Walls in adjusted position relative to the1 fixed Wall and abutted against said ral s.

2. A mold for building blocks comprising a base, a longitudinally extending relatively fixed partition wall, a vertically extending U-shaped strap mounted upon the base at one end of the said Wall and forming a socket for the end of said wall, and a socket for the opposite end of the wall attached to the base, U-shaped in plan, Whereby the wall may be removed from engagement with said brackets, side Walls adjustably mounted upon the base for movement toward or from the fixed wall and extending parallel thereto, andremovable partition plates operatively engageable with said fixed and adjustable walls.

In testimony whereof I hereunto alfix my signature in the presence of two witnesses. I
